I don't know if this is true, but I heard that lethal injection isn't actually that humane because there are 3 chemicals: 2 that stop the heart and breathing, and one that's a powerfull muscle relaxant. Apparently the muscle relaxant is so strong that it makes you unable to even make facial expressions, and the other chemicals make your organs burst and cause you incredible pain while unable to express it because of the relaxant. Does anybody know anything about that?
